function Check_Email($email)
{
if(eregi(".",$email) && eregi("@",$email))
{
$check = explode("@",$email);
if($check[1] == "") return false;
$fr = substr($check[1],0,1);
if($fr == ".") return false;
if(gethostbyname($check[1]) == $check[1]) return false;
if(gethostbyname($check[1]) == gethostbyname("lhalksjhdlkjashdlk.de")) return false;
return true;
}else{
return false;
}
};
with this function you can check with gethostbyname, if a emailadress is valid!
